Hey, I have been having this problem since past 3 days.
Gpu-GTX 960
The display either goes black and I get the message- 'monitor going to sleep'.
Or it turns brown or white and freezes until I restart by holding down the power button.
During this the cpu lights, and all the fans are spinning.
Sometimes I get a short stuttering sound before it goes out, other time I keep getting the entire sound output without any issues but the monitor doesn't get any signal.
Even when it crashes, sometimes it reboots itself, other time I have to hold down the button.
Twice I have gotten a completely back screen with 3-4 green dots/pixels at the same place when I am rebooting, it is fixed by rebooting again.
I monitored temperatures and they never go over 65-70 max. This happens when I'm gaming or just watch a stream or browsing.
I tried to do a clean reinstall of video drivers, and rolled back to a previous release as well.
Everytime the crash happens the fans and all the lights in the cpu are on. I also reset from the bios and am not running any overclocks anywhere.
If I turn the montior off and on, it say that dvi input is active but there is no display.
What may be the issue?
Edit:
I also did take the pc apart and re-place everything. But the gpu sits on the same pci slot.
